JOHN BARNETT, OF NEW YORK, N. Y.

,PLATE-HOLDER FOR PHOTOGRAPHIC CAMERAS.

SEECIFICATION forming part of Letters Patent No, 271,402, dated January 30, 1883. Application filed August 7, 1882. (No model.)

T 0 all w/Lom yit may concern Be it known that I, JOHN BARNETT, of New York, in the county and State ot' New York, have invented a certain new and useful Improvement in Plate Holders or Shields for PhotographicCameras, ot' which the following is a specification.

This improvement consists in aplate holder or shield comprising two shallow boxes, made of card-board or like material, and hinged together, one provided with guides or frames for a sensitized plate and shutter and the other adapted to close and lap over the edge portion ot' the former and make a lap-joint therewith.

The improvement also consists in the combination, ina plate holder or shield, ct' a shallow box having an opening in thefront, adark slide or shutter fitted to said box, a stopper, a cover hinged to the back ot' the box, and an elastic band serving to secure the cover, dark slide or shutter and stopper in place.

The improvement also consists in a plateholder frame covered or faced with a soft material over all the surface which is designed to be in contact with the camera, such soft material serving as a packing to prevent the entrance of light between the frame and camera.

rlhe improvement also consists in the combination ot' a camera, a traine detachably {itted thereto, and a plate holder or shield detachably iitted in said frame, the said frame being covered with a soft material over all its surface whichis'in contact with the said cam era and plate holder or shield.

The improvement also consists in the combination, with a frame, ot' a focusing plat-e having a flange approximately coincident with one face Aand adapted to be fitted into the frame so that the face ot' theplate will occupy a position corresponding to that which the face of a sensitized plate in a plate holder or shield would occupy, or to be reversed and titted into the frame so that it will not inter fere with the insertion of the plate holder or shield.

In the accompanying drawings, Figure l is a transverse section ot" a plate-holder and supporting'frame embodying my improvement. Fig. 2 is ahorizontal section ot' the same. Fig. 3 is atransverse section of the frame and focusingplate. Fig. 4 is a transverse section ofthe plate-holder. Fig. 5 is a horizontal sec` tion ot' a plate-holder slightly modified in form, and Fig. 6 is atransverse section ofthe saine.

Similar letters otJ reference designate corresponding parts in all the igures.

A designates a frame, of wood or other suitable material, located at the rear end of the 4body of a photographic camera, which maybe the front a beading, a, which tits snugly into the frame A. lliet'rame B is covered with soft material S-such as dannel-overall'its surface which is in contact with the camera-frame A and plate holder or shield D, and prevents the entrance of light between the frame B and camera A,'as also between the frame B and plate holder or shield D. At the back the trame B is provided with a rabbet, b, and a shallower rabhet, c. A rim, d, which may be made of any thin material-such, for instance, as cardboardis titted to the back ot' the frame in rear of both rabbets. rlhe plateholder D tits in the rabbet b, being held therein by the rim d.

The focusing-plate is made of glass, as usual. It is provided with atlange, e, which may be made ot' sheet metal or other suitable strong' thin material, and secured to the plate by being attached to a frame inclosiugthe edges of the glass, or in any other suitable manner. The iiange e is approximately coincident with the rear ofthe glass. Hence when the plate is introduced into the frame B, with its tlange e in the rabhet c, the face ofthe plate will occupy about the same position as that of a sensitized plate in the plate-holder, as may be seen in Fig. 3. When the plate-holder is to be inserted the focusing-plate is removed; but it may be reinserted with its face turned to the rear, as shown in Figs. l and 2, i'or it will not then interfere with the plate-holder, but will aid in retaining it in the frame B.

It is perhaps needless to remark that the rabbets b c are open at one end to permit the insertion and removal ofthe focusing-plate and sensitized-plate holder.

' I will now describe the plate holder or shield in detail. 1t consists essentially ot' two shallow boxes,ff, which may be made ot' card IDO i 271,4 ce

board, sheet metal, or other thin and light material, and are hinged together by a connect` ing-piece, of iexible material or otherwise, so that when they are shut together the part f will close or lap over the sides and ends,or the entire outer edge of the partf, and form a close joint, which will exclude light. The box j is at the front and the boxf is at the back of the plate holder or shield. The front of the boxjhas an opening, g, suitable for the exposure of the sensitized plate. The back of the box f is imperforate.

ln the box j' is a frame, h, which may be made of light strips of wood secured by an adhesive substance or otherwise to the ends and sides of the said box in such position that between it and the front ofthe box there will be left a slideway for the accommodation ot' a dark slide or shutter,f2. 'lhis slideway extends through the outer end of the box f -to admit ofthe insertion and removal ot the dark slide or shutter, and the corresponding end ot' the boxf is shown as mortised to t over the dark slide or shutter when it is in place. The strip h of the frame lz., located at'the opposite end ofthe box j', is shown as equal in thickness to the interior of the box, and as rabbeted to form a continuation ot the slideway.

E is the sensitized plate. It tits between the outer end ofthe box f and the rail h! of the frame h, and lies against the back of the other rails ot' the frame.

The oflice ot' the dark slide or shutter is to exclude light from the -sensitized plate until the plate is to be used.

The dark slide or shutter may be made of card-board or other suitable thin material. It is provided at the other end with a stopper,f3, which may by made ot' wood and excludes light from the slideway in which the dark slide or shutter works.

At the inner end the dark slide or shutter is preferably provided with a stop for preventing it from being drawn entirely ont ot' its sldeway. Such stop may consist of a lip, i, made ot' the same material as the dark slide or shutter, and turned or bent over.

rlhe stopper]v3 is provided with an elastic band of india-ruhber,f, or other suitable material, which may be slipped over the boxes j' f to keep them closed and to retain the dark slide or shutter and stopper in place. rlhis elastic band may be secured to the stopper by a staple, as shown.

The plate holder or shield may haveI a tab, f5, whereby it can be conveniently pulled out of the frame.

The plate holder or shield shown in Figs. 5 and 6 is in general construction like the one already described. Hence I need only describe the features wherein it diders.

The boxfhas a frame, h, which is of the same thickness as its interior, save that the rail which is at the outer end of the box is cut away to accommodate the dark slide or shut y terjz.

The slideway for the dark slide or shutter is for ned partly by the front of the box and partly by a frame, j, of cardboard or other suitable material, secured to the frame It. rl'he sensitized plate E rests on the 'framej and lits snugly within the frame It.

It will be seen that the frame B and the plate holder or shield D together take theplace of the plate holders or shields ordinarily used.

Any number ot' my plate-holders may be used with the same frame.

It is obvious that my plate holders are light, cheap, and exceedingly compact, and that a large number can be conveniently carried with a single trame for holding them.

The box f ot' my plate holder or shield constitutes a cover for the other box,j`. The two boxes may be regarded as a case.

The frame B may be held in place by pins lc entering recesses in the bottom and a catch, Z, at the top.

I desire to claim covering with a soft material not only the particular plate-holder frame shown and described, but even one which is a permanent part ofthe plate-holder.

What I claim as my invention, and desire to secure Letters Patent, is-

-l. A plate holder or shield comprising two shallow boxes made of card-board or like material and hinged together, one provided with guides or frames for a sensitized plate and shutter and the other adapted to close or lap over the entire edge portion of the former and make a lap-joint therewith, substantially as specified.

2. In a plate holder or shield, the combination of a shallow' box having an opening in the front, a dark slide or shutter ttted to said box, a stopper, a cover hinged to the back of the box, and an elastic band serving to secure the cover, dark slide or shutter, and stopper in place, substantially as specilied. n

3. A plate-holder frame covered or faced with a soft material over all the surface which is designed tobe in contact with a camera, such soft material serving as a packing to prevent the entrance of light between said frame and the camera, substantially as specitied;

4. The combination of a camera, a frame detachably iitted thereto, and -a plate holder or shield detachably iitted in said trame, the said frame being covered with a soft material over all the surface which is in contact with said camera and said plate holder or shield, substantially as specilied.

5. The combination, with a trame, of a focusing-plate having a flange approximately coincident with one face, and adapted to be iittcd into the frame so that the face ot' the plate will occupy a position corresponding to that which the face of a sensitized plate in a plate holder or shield would occupy, or to be reversed and tted into the frame so that it will not interfere with the insertion of the, plate holder or shield, substantially as specified.
